About this app

Create intelligent remote-control robots and vehicles using interactive in-app building instructions, with the LEGO® MINDSTORMS® Robot Inventor App! For use with the LEGO MINDSTORMS Robot Inventor (51515) set, this companion app has everything you need to build Charlie, Tricky, Blast, M.V.P. and Gelo, each with their own unique abilities. Then get ready to code and play your way through 50+ challenging activities.

A fun build-and-play experience
As you construct each robotic toy using the step-by-step building instructions in the app, you’ll complete a series of fun coding activities along the way. But if you prefer, you can also download a PDF version.

Coding, the fun way
If you’ve ever used a visual coding environment, you’ll be right at home with the Robot Inventor App’s colourful drag-and-drop canvas based on Scratch. Each coding element is grouped into categories so you can quickly find what you’re looking for. As well as using the coding canvas to complete the 50+ activities included in the app, you can also code your own activities for an even greater challenge – or, if you’re a more advanced coder, you can also use Python.

Take control
The Robot Inventor App includes a remote-control feature so you can get your robot walking, dancing and firing with just a few taps! You can also customise it to create your own personalised controller.

Learn while you play
While you’re building, coding and playing with your robots, you’ll also be exploring, experimenting and learning.

Advanced machine learning
Using your device’s camera or microphone, you can train your models to recognise and react to objects and sounds… even your own voice!

A community of fan models
The Community section of the app lets you build and code a growing collection of fun models submitted by some of our fans.

Share your cool creation
If you’ve designed and built your own amazing robot, you can take a photo of it and upload it to LEGO Life for everyone to see. You can also get loads more inspiration from what others have created.
